Description

I.I.

Изобретение относитс к изготовлению тонкостенных металлических труб.The invention relates to the manufacture of thin-walled metal pipes.

Известно устройство дл изготовлени тонкостенных металлических труб, содержащее корпус со смонтированными на нем направл ющим, лентопрофилирующим , формующим и обжимным механизмами , а также механизмом отрезки мерной трубы Со.A device for manufacturing thin-walled metal pipes is known, comprising a housing with guiding, tape-forming, forming and crimping mechanisms mounted on it, as well as a cutting machine mechanism, Co.

Устройство не позвол ет получать трубы требуемого качества и не обеспечивает необходимую производительность процесса.The device does not allow to obtain pipes of the required quality and does not provide the necessary process performance.

Цель изобретени - улучшение качества продукции и повышение производительности .The purpose of the invention is to improve product quality and increase productivity.

Указанна цель достигаетс тем, что в устройстве формующий механизм выполнен в виде барабана и охватывающей его втулки с двухвитковой винтовой проточкой на внутренней поверхности , а обжимной механизм выполнен в виде смонтированного над барабаномThis goal is achieved by the fact that in the device the forming mechanism is made in the form of a drum and the sleeves covering it with a double-turn screw groove on the inner surface, and the crimping mechanism is made in the form of mounted above the drum

И св занного с ним зубчатым зацеплением ролика. Первый виток винтовой проточки выполнен с пр моугольным, а второй с трапециевидным сечени ми.And the roller linked to it. The first turn of the screw groove is made with a rectangular, and the second with trapezoidal sections.

На фиг. 1 иоказано устройство, вид спереди-, на фиг. 2 - то же, вид сверху; на фиг. 3 - разрез А-А на фиг.2.FIG. 1 and the device is shown in a front view, in FIG. 2 - the same, top view; in fig. 3 shows section A-A in FIG.

Устройство содержит корпус со смонтированными на нем направл ющим механизмом 1, лентопрофилирующим меха10 низмом 2 с рабочими блоками 3, формующим механизмом, состо щим из ба рабана 4 и охватывающей его втулки 5 с двухвитковой винтовой проточкой 6 на внутренней поверхности. Обжимной The device comprises a housing with a guide mechanism 1 mounted on it, a tape-forming mechanism 10 with working units 3, a forming mechanism consisting of a drum 4 and sleeve 5 surrounding it with a double-turn helical groove 6 on the inner surface. Crimp

15 механизм выполнен в виде смонтированного над барабаном 4 и св занного с ним зубчатым зацеплением ролика 7. На корпусе смонтирован также механизм отрезки мерной трубы 8. Привод элеМ ментов устройства осуществл етс от двигател 9 через редуктор 10.15, the mechanism is made in the form of roller 7 mounted above the drum 4 and associated with gearing. The mechanism also cuts the measuring tube 8 mechanism. The elements of the device are driven from the motor 9 through the gearbox 10.

Claims

The configuration of the turns of the helical groove on the sleeve 5 is selected taking into account the high-quality molding of the seams of the resulting product. The steel belt from which the pipe is made enters the guide mechanism, from which it is fed into the tape forming and forming mechanisms. When winding on the drum 4, the tape is crimped by means of the frame 7, and the edges of the tape, the shape of the grooves 6 of the sleeve 5, form seams. As the pipe comes off the drum 4, it is cut by the mechanism 8 into dimensional lengths. The unit runs continuously in automatic mode until the tape runs out. After that, the end of the tape is automatically connected to the start of the next roll. The proposed device allows to obtain high quality pipes with high process performance due to the stability of operation of each of the functional units, which ensures the stability of the device as a whole. Claim 1. A device for the manufacture of thin-walled metal pipes, comprising a housing with mounted tape guiding, forming and pressing mechanisms, as well as a measuring tube cutting mechanism, in order to improve product quality and productivity ; The forming mechanism is made in the form of a drum and a sleeve covering it with a two-way screw groove on the inner surface, and the crimping mechanism is made in the form of a roller mounted above the drum and associated with it.

2. The device according to claim 1, which is the case in that the first turn of the screw groove is made with a rectangular, and the second with a trapezoidal section. Sources of information taken into account in the examination 1. Copyright certificate of the USSR No. 48085, cl. B 21 C 37/12, 1935.
